Conclusions
and Relevance Despite universal heparin thromboprophylaxis, nonleg
thromboses are found in 2.2% of medical-surgical critically ill
patients, primarily in deep veins and proximal veins. Patients who
have a malignant condition may have a significantly higher risk of
developing NLDVT, and patients with NLDVT, compared with those
without, appeared to be at higher risk of PE but not higher risk of
death.
